Baal Aadhaar Card Rules: Baal Aadhaar cards are blue in color, but very few people know about them. Generally, white Aadhaar cards include biometric updates, but Baal Aadhaar cards do not. Let's learn everything about the blue Aadhaar card in detail in this article.
Blue vs White Aadhaar Card: The Unique Identification Authority of India issues Aadhaar cards as an identity card for all citizens of the country. The Aadhaar card we typically see has a white background and is used by people of all ages as proof of identity. However, in addition to the white card, the UIDAI also issues a special "blue Aadhaar card," called "Baal Aadhaar."
The main reason for the color difference between these two cards is related to age limits, biometric data, and validity. Let's understand all the important rules related to this in this article.

- This includes 10 fingerprints, eye scan and face of the cardholder.
- Fingerprints and eyes of children below 5 years of age are not fully developed, hence biometric data is not captured in Blue Aadhaar.

Validity and mandatory biometric update rules
- The white Aadhaar card is valid for life and generally does not require frequent changes.
- The Blue Aadhaar card is valid only till the child is 5 years old, it becomes invalid after the child turns 5 years old.
- When the child turns 5 years old, it is mandatory to go to the nearest Aadhaar centre and update the biometric data (fingerprint, iris and photo).
- As soon as the biometric is updated, a simple white colored main Aadhaar card is issued in place of the blue Aadhaar card.

Required documents and how to apply
- For Blue Aadhaar Card, it is necessary to have the child's birth certificate and Aadhaar card of either of the parents.
- Apart from this, application for blue Aadhaar card of newborn baby can also be made by submitting the hospital discharge slip.
- This does not require any biometric verification, so you can easily get it made from the official website of UIDAI or the nearest Aadhaar centre.
